Phase 3 Track 1: File System Operations - Real Code Generation

[reza899]

Overview

Enable CoderAgent to perform real file system operations for code and test generation.

Current Status

• CoderAgent has mock implementations for file operations
• writeFailingTests and implementCode return simulated file paths
• Need real file creation, modification, and Git operations

Implementation Tasks

• Implement real file system operations in CoderAgent
• Replace writeFailingTests mock with actual test file generation
• Replace implementCode mock with real source code generation
• Add Git operations (staging, committing, branching)
• Implement file conflict detection and resolution
• Add workspace management and cleanup
• Implement atomic file operations with rollback

Acceptance Criteria

• Real test files created with proper Jest syntax
• Real source code files generated and compilable
• Git operations working (add, commit, branch)
• File conflicts detected and resolved
• Workspace isolation for concurrent operations
• Zero mock file operations in CoderAgent

Testing Requirements

• Write integration tests with real file system
• Test Git operations and conflict resolution
• Test workspace isolation and cleanup
• Validate generated code quality and syntax

Priority: P0 - Critical
Phase: 3
Track: 1 - Core Integration
Estimated Effort: 4-5 days

🔄 Enhancement Update: This issue will now be enhanced with BAML integration (Issue #20)

BAML Integration Benefits:

• Type-safe file generation prompts with schema validation
• Structured code templates and formatting
• Multi-model support for different code generation tasks
• Enhanced error detection in generated code

Updated Implementation:

• File operations will use BAML-validated specifications
• Code generation templates structured through BAML schemas
• Integration with Issue Foundational Enhancement: BAML Integration for Structured Agent Communication #20 for foundational BAML setup

Timeline: Week 1 implementation following BAML foundation setup.

🔄 BAML Foundation Ready - Core Implementation Still Needed

BAML Integration Completed ✅

• ✅ File Operations Schema: Complete coder-agent.baml with TDD and file operation schemas
• ✅ Type-Safe Functions: generateTestSpecification, implementCodeFromTests, planFileOperations
• ✅ Code Generation Schemas: Comprehensive types for test specs, code implementation, refactoring
• ✅ Validation Framework: Input/output validation for all file operations

Still Required for Completion ❌

• ❌ Real File System Operations: Replace mock writeFailingTests and implementCode
• ❌ Git Integration: Implement staging, committing, branching operations
• ❌ File Conflict Resolution: Handle file conflicts and workspace management
• ❌ Atomic Operations: Rollback capability for failed operations
• ❌ Workspace Isolation: Concurrent operation safety
• ❌ Integration Tests: Tests with real file system and Git

BAML Enhancement Benefits

With BAML foundation complete, this implementation will have:

• Schema-Validated Code Generation: Type-safe test and source code creation
• Structured File Operations: Validated file paths, content, and metadata
• Error Recovery: BAML validation prevents malformed file operations
• Multi-Language Support: Foundation ready for multi-language expansion

Status: Foundation ready, core file system implementation pending
Next: Implement real file operations with BAML-validated specifications
